Abstract

The method of electrical images has been used to derive an expression for the difference in potential between two points close to a good conducting sphere in a poor conducting medium. The results indicate that the presence of a conducting ore body of commercial size near a drill hole can be detected by suitable electrical measurements made in the hole. The results of a test of the method in a drill hole near a small conducting sulphide ore body are given.
